serial: imx: remove the DMA wait queue
The DMA wait queue makes the code very complicated: For RX, the @->stop_rx hook does not really stop the RX; For TX, the @->stop_tx hook does not really stop the TX. The above make the imx_shutdown has to wait the RX/TX DMA to be finished. In order to make code more simple, this patch removes the DMA wait queue. By calling the dmaengine_terminate_all, this patch makes the RX stops immediately after we call the @->stop_rx hook, so does the TX.
